RALPH ALTMAN, WALTER L. WOOLEY, AND OTTO F. SOTER, OF ST. LOUIS, MISSOURI.

STORMPROOF-DOOR THRESHOLD.

Application filed April 27, 1921.

To all whom, it may concern.'

Be it known that RALPH AL'rMAN, lVAL'rnR L. W'ooLEY, and O'rro F. Sormn, citizens of the United States of America, residing at St. Louis, in the county of St. Louis City and State of Missouri, have invented new and useful Improvements in Stormproof- Door Thresholds, of which the following is a specification.

The object of the invention is to provide simple and efiicient means for closing the interval between a door and the threshold bar or sill as a means of effecting an air and weather tight joint when the door is in its closed position, and more especially to rovide a device for this urpose which is lirought into operative position by the closing of the door and is permitted to move into unobstructive relation with the door opening when the door is opened; and with these objects in view the invention consists in a construction and combination of parts of which a preferred embodiment is shown in the accompanying drawings, wherein Figure 1 is an elevation of a portion of a door and frame, partly in section, and showing a weather strip structure embodying the invent-ion applied in the operative position thereto.

Figure 2 is a cross sectional view of the same.

Figure 3 is a plan view showing the door jambs in horizontal section.

Figure 4 is a detail view of one end of the apparatus detached from the door structure.

The device consists essentially of a horizontal substantially fiat weather strip 10 normally seated upon the upper surface of the door sill or threshold bar 11 and in such relation thereto as to afford no obstruction to passage through the doorway, said strip having a depending web 12 extending through a suitable vertical guide slot 13 in the sill and preferably provided at its lower end with a foot 14 operating in a longitudinal recess or channel 15 in the under side of the sill, together with a trip 16 tiltably mounted in the door frame and consisting of an upright arm 17 having a cam faced ear 18 for engagement by the edge of the door 19 in the closing movement of the latter,

reaches its closed position.

and an arm 2O extending under the web of the weather strip, into the recess or channel 15 for contact with the foot 14.

The side member or jamb 21 of the door frame should be cut away or recessed as indicated at 22 to receive the trip which is held in such position as to cause the projection of the cam ear 18 into the door rabbet 23 when the door is open, and thus dispose the beveled or cam face thereof in the path of the door as the latter is swung to its closed position. The trip is duplicated preferably at both the free and hinged edges of the door so that while the free edge thereof strikes the cani face of the ear 18 and tilts the trip by sliding upon said face, the hinged edge of the door engages the ear and represses it in the plane of the door to e'ect a tilting movement thereof and thereby the bodily el-evation of the strip to bring the upper surface of the latter into Contact with the lower edge surface of the door as it The trips are preferably of yielding material affording a suflicient spring action to insure a yielding contact of the strip with the bottom edge of the door without unnecessary straining the parts and yet sufli'cient to compensate for any slight variation in the interval between the lower edge of the door and the surface of the sill, or any variations which may be incident to shrinkage or expansion incident to climatic or weather conditions.

Having described the invention what is claimed as new and useful is 1. The combination with a door sill of a weather strip disposed longitudinally upon the surface thereof and provided with a de- Yao pending web movable inV a guide slot in the sill and terminating at its lower edge in a foot, and angular trips tilta-bly mounted in the door frame with inwardly extend-V ing arms terminally disposed in operative relation with said footV and upwardly ex- A tending arms having terminal inwardly projecting trip ears arranged in the paths of movement of the free and hinged edges of the door.
